The impact of environmental protection tax on the health of middle-aged and older adults: evidence from CHARLS data in China.

Introduction: With the aging population, the relationship between human health and the ecological environment has gained increasing attention. In China, it is imperative to evaluate the policy effects of the Environmental Protection Tax (EPT) on improving the ecological environment and enhancing the health of middle-aged and older adult people. Methods: This study, based on data from the China Health and Retirement Longitudinal Study (CHARLS), employs a Difference-in-Differences (DID) model to assess the health effects of the EPT policy. Results: The findings indicate that the EPT policy significantly improves the health of middle-aged and older adult individuals and reduces the prevalence of chronic diseases. The EPT policy affects the health of middle-aged and older adult through two main mechanisms: emission reduction and psychological effects. These are evidenced by reductions in PM10 particle concentration and sulfur dioxide emissions, improvements in public sleep quality and memory, and significant changes in environmental awareness and concern. Discussion: Heterogeneity analysis reveals differences across urban and rural areas, age groups, and education levels. Following the implementation of the EPT policy, there are notable improvements in reduction of chronic diseases among rural residents, self-rated health among urban residents, and overall health among the older adult and individuals with a junior high school education or lower. The study's results confirm the importance of environmental policies in promoting public health, providing a reference for the refinement of the EPT system, and offering insights for environmental pollution control in developing countries.

Does high-speed rail stimulate university technology transfer? evidence from China.

Prior studies ignore the impact of infrastructure on university technology transfer. High-speed rail, China's most significant infrastructure, has played an essential role in the economy and society. Using high-speed railway construction as a quasi-experiment and a large sample of Chinese universities for the 2007-2017 period, we investigate the impact of high-speed rail on university technology transfer. We provide extensive evidence that high-speed rail has a positive effect on university technology transfer. The finding remains valid after a battery of robustness tests. Mechanism tests find that high-speed rail can improve university technology transfer by promoting the interaction between universities and enterprises and improving enterprises' technology demand for universities. Further analysis shows that better intellectual property protection strengthens the effect of high-speed rail on university technology transfer, and the relationship between high-speed rail and university technology transfer is more prominent in the regions with underdevelopment technology trading markets. Our study suggests that high-speed rail is an important variable that affects university technology transfer.

The influence of prepaid service and promotion purchase restriction on consumers' willingness to share in tourism and hospitality: from the perspective of framing effect theory.

Prepaid service is not only a financial tool, but also a common promotion mode in tourism and hospitality. Due to the limited resources of the enterprise, the enterprise needs to reasonably allocate the promotion resources to maximize the effectiveness of the promotion. As two common promotion purchase restrictions, limited-time promotion and limited-quantity promotion how to interact with prepaid services in the form of discounts or freebies to enhance consumers' willingness to share is the focus of this study. This study carried out three experiments based on framing effect theory, stimulus-organism-response theory, and social capital theory, which has found that the prepaid service mode moderates the relationship between promotion purchase restrictions and consumers' willingness to share. When the prepaid service mode is a discount type, the limited-quantity promotion can generate higher sharing willingness than the limited-time promotion, and the perceived scarcity plays a mediating role. When the prepaid service mode is a freebie type, the limited-time promotion can generate higher sharing willingness than the limited-quantity promotion, and the perceived certainty of opportunity plays a mediating role.
